HORSE HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 268,111, dated November28, 1882,

Application filed January 13, 1882. (No model.)

To all whom it mag concern Be it known that I, TYLER O. LORD, of thecity of Joliet, in Will county, and State of Illinois, have inventedcertain new and useful Improvements in Horse Hay-Rakes, the constructionand operation of which I will proceed to explain, reference being bad tothe annexed drawings, making a part of this specification, in which-Figure 1 is a plan view; Fig. 2, a vertical cross-sectional view on theline a: in Fig. 1; Fig. 3, a front elevation of the two ratchetwheelsz'on the continuously-revolving rakehead; Fig. 4, a plan view on the topofa tooth and the lifting-bar, showing the attachment of the tooth tosaid lifting-bar; and Fig. 5, a side View of the upper end of a tooth,showing its relation to the rake-head.

This invention relates to certain improvements in horse hay-rakessuch-as are in ordinary use; and it consists principally in theconstruction of the rake-head and the devices for operating the liftingof the teeth to discharge their load, as particularly pointed out in theclaims.

Referring to the drawings, A are the'two traveling wheels, that supportthe machine and rotate on the axle m, which consists simply of astraight loose rod. The arms S rest upon the axle m and support at theirfront end the stripper-bar D and a pair of ordinary shafts, girths,seat-board, &c., which I do not further describe, as they do not formany part of this invention. The rear end of the arms S are formed intoboxes that receive and support the outer ends of thecontinuously-revolving divided rake-head B, while the inner ends of thesaid rake-head are supported and revolve in the boxes on the rear endsof the arms 0 near the central part of the machine, as shown in Fig. 1.The inner ends of the hubs of the wheels A are formed in the shape ofsprocketwheels, and also so are the outer ends of the revolving dividedrake-head B, as shown in said Fig. l, and the endless chains S connectthe two so that the revolving rake-heads B are driven by the hubs of thewheels A by means of the endless chains S and rotate continuously in thedirection the machine travels.

Each part of the revolving rake'head B is septhe parts or each other topermit the machine to be turned around or backward. The inner ends ofthe two parts of the rake-head B approach each other very closely-nearthe center of the machine, and each is furnished with a rigidly-fixedratchet-wheehz, (shown more particularly in Figs. 2and 3,) which ofnecessity rotate with and in the same direction as the revolvingrake-head B. Immediately in the rear of the said ratchets z is located apawl for each ratchet, which pawl It stands hinged to the lifting-bar cat itsfront. A spring, 20, stands under the pawls n and supports themboth at once in an upright position, so as to be free from contact withthe ratchets 2, as

shown in Fig. 2, until it is desired to bring 79 them in contact.

When the operator desires to raise the teeth a to discharge their loadhe bears down with his foot on the cord 0, which pulls the upper end ofthe pawls it forward, causing the catch n" on the under side of thepawls n to engage with the teeth of the ratchets z as they rotate, whichelevates the lifting-bar c, with the teeth a, which pass through it,carrying it upward and forward until the pawls 'n are carried for- 80ward far enough to engage with the adjustable stop c immediately infront of the ratchets z, causing the catch it of the pawls n todisengage with the ratchets, while the spring 10 holds the pawls u up intheir original position after the foot is off the cord 0', and lets therake-teeth a fall to the ground to gather up another load. The pawls nand ratchets z are separated, so that either one will elevate thelifting-bar, as set forth, independently 0t the other, so that the teetha may be elevated even while the rake is being turned about, as theouter traveling wheel will rotate one part of the rake-head andratchets, and perform the operation of lifting the rake-teeth, asdescribed. 5

The stop 0 is attached to the machine in such a manner that it may beadjusted up or down to engage with the pawls n sooner or later, so as toregulate the height to which the teeth a are elevated from the ground.The upper end of the teeth a are formed in the shape shown in Fig. 4, inthe shape of an L, and lie in a corresponding recess in the cap 0' ofthe lifting-bar, as is also shown in Fig. 2.

The cap 0 is attached to the top of the lifting-bar c by means of boltsor screws, as shown in Fig. 4, after the teeth are all placed in theirrespective places between them, and this is the only fastening t0 themachine the teeth a have. Thetceth bend around the revolving rake-head Bloosely,'as is shown in Fig. 5, to allow the drop or play up and down ofthe teeth as they travel along, and then return through the 'tooth-board0 through a separate aperture of just the diameterof the tooth afterleaving the rake-head. When itis desired to hold the teeth up off theground to travel from one field to another, so as not to rake, thelevers a", r, and 1" are used. The lever r attaches to the standard n onthe arm 9, Fig. 1, which arm g is is hinged to the rake-head B andbolted to the lifting-bar 0, so that when the lever r is pulled towardthe seat it will elevate the rake teeth a and lifting-bare for saidpurpose. The stripper-bar D is arranged on the under side ofthe machinein front of the axle in, and bears the stripping-teeth R in the ordinarymanner. The

ratchet-wheels z are inclosed in hoods H to prevent them from beingclogged by hay or other obstruction. Similar hoods, H, are arranged tocover and protect the endless chains S.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent is as follows, to wit:

1. In a horse hay-rake, the rake-head B, constructed in two equal partsand supported on the axle m by the arms S and 0, and arranged to revolvecontinuously independently of each other by means of the endless chainsS, and provided on their inner ends with the ratchets z and pawls n toelevate the tooth-board 0, containing the teeth a, in the manner setforth. 2..In a horse hay-rake, the teeth a, hinged in the tooth-board c.as shown, and arranged to inclose the rake-head B loosely and returnthrough a separate aperture having a diameter coextensive with that ofthe tooth in the tooth-board, whereby the portion of the teeth inclosingthe rake-head B is free to oscillate up and down-by reason of such looseinclosure, as set forth.

TYLER O. LORD.
